Question : 15 of 200

Marks: +1, -0

Select the option that is related to the third number in the same way as the second number is related to the first number.
24 : 5 :: 48 : ?

Solution:

The logic follows here is :

\text " First number "= \text "(Second number)"^2 - 1

Or,

\text " Second number "= √ \text "(First number + 1)"

For 24 : 5,

5 = √ (24 + 1)

5 = √ 25

5 = 5.
For 48 : ?

? = √ ( 48 + 1)

? = √ 49

? = 7

Hence, the correct answer is "7".
